How it works:

Our PHI-CELL® technology is a proven technology with over 4 million units in use worldwide.  The Guardian Air QR+ active air purification solution disperses airborne hydrogen peroxide throughout your air conditioning system and living spaces, reducing viruses, bacteria, mold spores and odors at the source.  As Mother Nature’s chosen sanitizer, hydrogen peroxide is incredibly effective at reducing these contaminants in your home or office, just as it is outside.

This system can be easily incorporated into your existing air conditioning ductwork. Unlike passive air technologies, which need pollutants to pass through the unit for purification or filtration, the Guardian Air QR+ in-duct air purifier sweeps through the air-conditioned space actively purifying pollutants at the source.

Why it matters:

The indoor air quality in your home or office can be five times more polluted than the outdoor air, primarily because the indoor air space is unable to match the purification processes that occur in nature. We have added contaminants that are simply not filtered out of the air or removed from surfaces, but instead accumulate again over time. This happens because bacteria, viruses, mold spores, and other air toxins are sometimes too small to be stopped by standard, passive filtering methods.

So, since you spend up to 90% of your time indoors, it’s important to consider the impact these pollutants can have on your long-term health. When you install a Mini Split PHI on your ductless system, you will notice the difference in the quality and freshness of the air you breathe and wonder why you did not take this simple measure sooner.

The Guardian Air QR+ active air purification solution disperses airborne gaseous hydrogen peroxide throughout your air conditioning system and living spaces, reducing viruses, bacteria, mold spores and odors at the source. 

It operates silently and continuously, so once it’s installed, the only thing you’ll notice is how fresh your home smells – and how comforting it is to help protect everyone around you.

  • Installation is quick and easy
  • One of the least expensive components of an air conditioning system, but one that can have one of the biggest impacts on your air quality.
  • Active technology reduces viruses, bacteria, mold spores and odors right at the source to give you the freshest air possible.
  • Can be easily integrated into your existing air conditioning duct system.
  • Reduces odors from mold, pets and smells from old homes.
  • Silent, continuous operation so you only notice how fresh your home is.

The Guardian Air QR+ can be installed in any existing air conditioning ductwork in homes or offices.

  • Reducing Odors – If you have a room that smells like mold, but no matter what you do, it does not seem to solve the problem. Or you have a smelly pet – our system is designed to reduce those odors.
  • Spread of viruses and bacteria – especially in this day and age, we all want to do everything we can to prevent the people we care about from getting sick from contaminated air and surfaces in our homes. Our system helps reduce the spread of pathogens in the air and on surfaces in your building.
  • Home Application – You will notice the difference in air quality immediately, which will improve the quality of life in your home. Our system also works in homes without central air conditioning.
  • Office Application – There is plenty of research that makes a direct correlation between indoor air quality and the satisfaction and productivity of your employees. Not to mention the reduction in sick time and the noticeable difference your customers will feel when they walk into your office.
  • Hotel Applications – One of the biggest complaints you read about on forums is the bad smell in the room. Not only does this put off regular customers, but it also affects all those who are researching before coming in. Do you know how this affects your occupancy rate and the annual opportunity cost associated with it? This solution could save you a fortune in opportunity costs for a comparatively small investment.
